In the automAtic cutoff engine. the
governor acts directly upon the cutoff
valve, prolonging the period OF admis-
sion when the work is heavy, and short
ening it when the work is LIGHT
Engines 80 governed or regulated are
called automatic engines
A METHOD of making embossed sheet
tin and other like material, in imitation
of finer grades Of material, consists in
uniformly applying yielding lacquer
to the sheet to produce the appearance
of the metal initiated, and then emboas-
ing or impressing the same.
In guiding belts on or of, it is best
to protect the hand with piece of cloth
held In the hand, but never wrapped
around it or the wrist or arm. A stick
is liable to be caught by the pulley or
belt, drawn between the pulley and
belt into other machinery, or thrown
swiftly, striking you or some one else.
AN improvement in steel forgings
consists in casting an ingot whose
transverse section is greater in one di-
rection and less in another than that of
the forging desired, so as to induce q
lateral instead of longitudinal flow
Of its metal under pressure, and con-
verting said ingot or casting into a forg-
ing by reducing it to the desired form
by the application Of pressure between
forming dies.
In steam engines governed by the
throttling method, the governor acts
upon q valve placed in the steam pipe,
admitting more or less steam according
to the speed at which the engine is
running, more steam being admitted
when the engine is heavier loaded, and
consequently slight falling off in
speed, and less steam permitted to en-
ter the cylinder when the load is light,
and the speed consequently greater.
Thus the governor valve acts as throt-
tie valve, throttling the steam more or
less according to the requirements of
steam pressure and load.
The bricks for chimney-top, should
be soaked In water few minutes, so
that they will not extract the water
from the mortar. In order to have
mortar become very hard, it must dry
slowly. By laying up wet bricks, the
mortar will set slowly, and eventually
become almost as hard as the bricks
Every brick chimney should be covered
with copestone, with an arched top or
with bricks placed over the fues, like
the rafter of building, for the purpose
of turning off the water which would 90
down the inside, be absorbed by the
bricks, and, in some instances, soak
through and wet the paper or kalsomin.

The wonderfully well-colored articles
OF bronze, now seen in the market, and
showing all tints, and adhering thor
oughly to the metal, is a French pro-
cess, but it is no longer . secret. The
method of manufacture lies in the use
of solutions of sulphides of anthony
and arsenic which were applied to tho
bronze or brass articles. After thor.
oughly washing them with water, since
every trace of acid left in picking
would show black spots, they are thor
oughly dried, and then the sulphida
solution is applied with q brush. The
best way is to begin with dilute solp.
ton of ammonia, giving one application.
After drying, the coating is brushed,
and then the dilute solution of sulphide
of arsenic in ammonia is used, which
produces yellow color. The oftener
this sulphide of arsenic is applied the
browner will be the color, and deep
tint may thus be finally obtained. By
solutions of sulphide of antimony, either
in ammonia or in sulphide of ammonia,
the tint is reddish, and it is possible in
this way to obtain either the most deli
cate red or the deepest dark red. II
some of the parts of the article are
rubbed more strongly high metallic
luster is obtained. Ammonia or sui
phide of ammonia reabsorbs the bronz-
ing, and in this way defective spots may
be improved. It is possible also to use
solutions in caustic soda or potash, or
the sulphides of either.
